Set Appliance State:

Turn Hot Water Tap On
CH & DHW temperature controls set to Max
WARNING! - Mains voltage is expected during test follow
TOPs P4 live testing procedure
Mains Power On

Observation:

Allow boiler to ignite and run for DHW demand.
This boiler has an electronic flow control valve which limits the hot water flow rate until the set temperature is reached, thus reducing the waste water time when a tap is opened (Default setting). It is possible that this function may have been deactivated (parameter A1) depending on customer requirements & a fixed flow rate mode or other selected.
Is the DHW operation satisfactory?
Note.
Flow rates higher / lower than specified will result in a higher or lower temperature rise, this must be taken into account when selecting the outcome of this test
